1Reliability
If a reservoir device is implemented using conventional electronic circuits without sample and hold circuits, then the device structure remains simple, but the short term memory property is insufficient and performance deteriorates
Solution Approach 1:
The sample and hold circuit is nested within each node of the reservoir device, with capacitors and switches integrated into the node structure. This allows the memory function to be embedded at the circuit level without requiring separate external memory components, thus improving short term memory property while controlling overall device complexity.
Solution Approach 2:
The sample and hold circuit acts as an intermediary between the input signal terminal and the output terminal, temporarily storing input signals and propagated signals during the computation process. This mediator enables the device to retain past information for the necessary duration to achieve optimal short term memory property.
2Productivity
If only recent data is used for processing in time-series data, then the device complexity remains low, but the performance is insufficient due to poor short term memory property
Solution Approach 1:
The sample and hold circuit performs preliminary action by capturing and holding input signals before they are fully processed. This allows the device to prepare and retain data at the appropriate moment, ensuring that past information is available when needed for computation, thereby improving performance in time-series data analysis.
Solution Approach 2:
The reservoir device utilizes feedback connections where output signals are fed back to input terminals through the sample and hold circuits. This feedback mechanism allows the device to consider past information and maintain short term memory, improving its ability to process time-series data effectively.
